> Are you still seeing device timeouts?

No, once I got interrupts properly working on this box with various
fixup issues, all works well.  ACPI seems to have made the most
progress.  Sound even works, as do all the PCI devices.

The laptop has the lucent card.

AP's are WAP-11 and Airport (old, grey one with a lucent card)
although I took the card out of it to try it in the host, so right now
we only have WAP-11's.

As I said, they were identical.  I did the traces from a linux box
listening to the air, and it returned the same packet as the wire.  I
can easily give traces from the wire, not so from the air.

The HOST does not see the problem, in that if I run tcpdump -i wi0,
all looks fine, but the packets are not being transmitted correctly,
sometimes.

There was a change in the 8.10 firmware to fragment 11 Mbps encrypted
packets into smaller chunks, to work around some sort of AP issue.
However, I'm seeing the same loss with the 6.x firmware too, so that's
not the full issue.
